Cpe Protected - Cisco Catalyst 2950 Command Reference Manual

Chapter 2 Catalyst 2950 and 2955 Cisco IOS Commands

cpe protected

Use the cpe protected interface configuration command to restrict data traffic to individual ports on
Cisco 585 LRE customer premises equipment (CPE) ports. Use the no form of this command to allow
different ports on the same CPE device to exchange data directly.
This command is available only on Catalyst 2950 Long-Reach Ethernet (LRE) switches.
Syntax Description
port port-id
Defaults Traffic is not restricted to specific ports.
Command Modes Interface configuration
Command History Release
12.1(11)YJ
Usage Guidelines Even though you can protect an LRE interface by using the switchport protected interface configuration
command, this command does not protect individual CPE Ethernet ports. Use the cpe protected
command to ensure that data traffic from one CPE port is not accessed on any of the other three ports.
Use the cpe protected command to restrict CPE traffic, either at the CPE device level or at the individual
port level for data security. Use the cpe protected command without specifying a CPE port to protect
data for all applicable CPE ports. Use the cpe protected port port-id command to protect a specific CPE
Ethernet port.
When using this feature, always specify a minimum of two ports. A single port that is configured as
protected has no effect. Data traffic does not flow between two ports that are protected.
Examples This example show how to protect CPE port 1 on an LRE port:
Switch# configure terminal
Switch(config)# interface longreachethernet0/1
Switch(config-if)# cpe protected port 1
